Bonfire : Check for Palindrome.

They mention here that we should remove all punctuation marks in the string.

Here are the strings  in the Bonfire test cases with punctuation marks.
"A man, a plan, a canal. Panama"
"My age is 0, 0 si ega ym."
"0_0 (: /-\ :) 0-0"


Used little bit of stackoverflow and MDN to understand .replace()
This is what I got:

Used a lot of console to debug each string and that really helped.



Code starts here

function palindrome(str) {
  
  // Good luck!
  //Removing punctuation marks and spaces in original string..
  var originalstring = str.replace(/[.,-\/#!$%\^&\*;:{}=\-_`~() " "]/gi,"").toLowerCase();
  var reversedstring = str.replace(/[.,-\/#!$%\^&\*;:{}=\-_`~() " "]/gi,"").toLowerCase().split("").reverse().join('');
  if(reversedstring === originalstring)
    {
  return true;
    }
  else
    {
      return false;
    }
}




palindrome("eye");

Factorial of Number Bonfire Solution

Used a while loop for this and it worked ok.

function factorialize(num) {

  factorial = 1;

  i = 1;

  while(i<=num)

    {

      factorial = factorial * i;

      i++;

    }

  return factorial;

}

factorialize(5);

Bonfire Reverse a String.

Was able to solve this using MDN examples and console.log() in chrome browser.
Solution:


function reverseString(str) {
 
  return str.split("").reverse().join('');
}

reverseString("hello");

Here goes the story for starting this blog.
1.There is not much going on at work and the next release for my project is slated to start Novemeber mid so I have a lot of time to kill, so  i thought why not learn D3.js.
I currently work with QlikView and feel extremely frustrated at some of the limitations for the visualization we can do with it.
Took a look at D3. js charts by Mike Bostock and woah, I'm like I want to be able to create them from scratch.

Also my coding skills have gotten little rusty over the past two years and hence learning D3 as a ruse to sharpen them.
Started with CodeAcademy but i felt its okay for learning syntax and basics for JS,HTML and CSS.

I came across freecodecamp after that now Im totally absorbed doing these Bonfire challenges.

Feeling really bad that I didnt get to do such stuff in my Engineering.
Also i started learning Python with Coursera's Rice University Course but I get distracted really easily.

FreecodeCamp is working out good so far because i like to learn by doing stuff.

On the work front I still have loads to learn, but need to make time for it.

Bonfire : Where do I Belong

function where(arr, num) {
  // Find my place in this sorted array.
   arr.sort(function(a, b) {
  return a - b;
});
 
//at this point the array is all sorted
 //the below function gets the maxnumber in the array
  function maxnumberinarray( array ){
    return Math.max.apply( Math, array );
};
  if(num>maxnumberinarray(arr)){
    return arr.length;
  }
  var pos = 0;
  for(i=0;i<arr.length;i++)
    {
      if(arr[i]<num){
        pos = i+1;
      }
      else {
      return pos;
      }
    }
}

where([10, 20, 30, 40, 50], 35)
